REQUESTS NUMBER Cumulative number of requests that were executed in the consumer group
CPU_WAIT_TIME NUMBER Cumulative amount of time that sessions waited for CPU
CPU_WAITS NUMBER Cumulative number of times all sessions in the consumer group had to wait for CPU
CONSUMED_CPU_TIME NUMBER Cumulative amount of CPU time consumed by all sessions in the consumer group
YIELDS NUMBER Cumulative number of times that sessions in the consumer group had to yield CPU to other sessions because of quantum expiration
QUEUE_LENGTH NUMBER Number of sessions waiting in the queue
CURRENT_UNDO_CONSUMPTION NUMBER Current amount (in kilobytes) of undo consumed by the consumer group
ACTIVE_SESSION_LIMIT_HIT NUMBER Number of times that sessions in the consumer group were queued because the consumer group reached its active session limit
UNDO_LIMIT_HIT NUMBER Number of times that queries in the consumer group were cancelled because the consumer group reached its UNDO_POOL limit

IDLE_BLKR_SESSIONS_KILLED NUMBER Number of times that sessions in the consumer group were killed because they were idle too long (reached MAX_IDLE_BLOCKER_TIME) and were blocking other sessions
QUEUED_TIME NUMBER Total amount of time that sessions in the consumer group have spent in the QUEUED state because of the active session limit
QUEUE_TIME_OUTS NUMBER Number of times that requests from sessions in the consumer group timed out because they were queued for too long (reached QUEUEING_P1)
